ROLLS ROYCE & BENTLEY MOTORS.

Rolls-Royce Limited was a renowned British car manufacturing company and, from 1914 on, aero-engine manufacturing company founded by Charles Stewart Rolls and Sir Frederick Henry Royce on 15 March 1906 as the result of a partnership formed in 1904.
In 1971, Rolls-Royce was crippled by the costs of developing the advanced RB211 jet engine, resulting in the nationalization of the company as Rolls-Royce (1971) Limited. In 1973, the car division was separated from the parent company as Rolls-Royce Motors. Rolls-Royce (1971) Limited continued as a nationalized company until it was privatised in 1987 as Rolls-Royce plc.
Bentley Motors Limited is a German owned British manufacturer of luxury automobiles founded on 18 January 1919 by W. O. Bentley. Bentley had been previously known for his range of rotary aero-engines in World War I, the most famous being the Bentley BR1 as used in later versions of the Sopwith Camel. After the war, W. O. Bentley designed and made production cars that won the 24 hours of Le Mans in 1924 and following models which repeated those successes each June 1927, 1928, 1929, and 1930.
Purchased by Rolls-Royce in 1931, when the factory was sold, and production stopped for 2 years, it was revived as as a Rolls based sports car at the Rolls-Royce factory in Derby, and later in Crewe. The business, minus the Rolls Royce name, has been owned by the Volkswagen Group of Germany since 1998. The business is now based in Crewe, Cheshire, England, with the Central Production Facilities there. As of November 2012, China is the largest market for Bentley automobiles.
